關於php的判斷語句,該怎麼處理

關於php的判斷語句

$pubdate = $dsql->GetOne("select pubdate from article where writer ='".$writer."' order by id desc limit 1");
if((time()-$pubdate['pubdate'])<(3600*24)){
ShowMsg("對不起，一個會員每天只能發一篇文章！","-1","0",5000);
exit;
}

以上判斷一個會員在一天內只能提交一篇文檔，想修改成可以提交3篇，應該怎麼做？

------解決方案--------------------
原代碼改為

$n = 1; //你指定的篇數
$pubdate = $dsql->GetOne("select count(*) as cnt from article where FROM_UNIXTIME(pubdate,'%Y%m%d')=DATE_FORMAT(now(),'%Y%m%d') and writer ='".$writer."' order by id desc limit 1");
if($pubdate['pubdate'] > $n){
    ShowMsg("對不起，一個會員每天只能發 $n 篇文章！","-1","0",5000);
    exit;
}
